3. INTRODUCTION
Environmental Impact Assessment (EIA) is a process which
ensures that all environmental matters are taken into account
quite early in the project at planning process itself.
It takes into consideration not only technical and economic
considerations but also, traditional aspects like impact on
local people, biodiversity etc.
5. EIA is intended to prevent or minimize potentially
adverse environmental impacts and enhance the
overall quality of a project. The main benefits
and advantages of EIA are:
Lower project costs in the long-term
Increased project acceptance
Improved project design
WHY EIA?
6. The EIA Directive requires projects likely to
have significant effects on the Environment
by virtue of their nature, size or location to
undergo an environmental assessment before
the competent authority in question grants
consent.
The EIA Directive defines a project as the
execution of construction works or of other
installations or schemes,
other interventions in the natural
surroundings and landscape including those
involving the extraction of mineral resources.
THE EIA DIRECTIVE
7. The EIA should identify, describe and assess
the direct and indirect effects of a project on
the following factors:
Human beings
Fauna and flora
Soil, Water & Air
Climate and the landscape
Material Assets
Cultural Heritage
Interaction between all above factors
EIA therefore should have a very strong social
dimension
8. Started in 1976-77, when Planning Commission asked
Department of Science & Technology to examine River
Valley Projects from environmental angle
Till 1994, Environmental Clearance from Central
Government was an administrative decision which lacked
legislative support.
On 27th
January 1994, Union Ministry of Environment &
Forests, GOI under Environment (Protection) Act 1986,
promulgated EIA notification making Environment
clearance mandatory for expansion or modernization of
any activity or for setting up new projects listed in
Schedule one of the notification, which have been
amended more than 12 times.
HISTORY OF EIA IN INDIA
12. Environment Impact Assessment
EIA Clearance required
Total EIA clearance is required for 32 categories of developmental
works broadly categorized into following industrial sectors:
Mining
Thermal power plant
River valley
Infrastructure (Road, highway, ports, harbour, airports,
Industries including very small electroplating or foundry units)
Certain activities permissible under Coastal Regulation Zone Act 1991,
also require similar clearance

14. Screening
• It would be time consuming and a waste of
resources for all proposed projects and activities
to undergo EIA
• Not all development projects require an EIA, as
some projects may not pose an environmental
threat
• Screening is the process used to determine
whether a proposed project or activity requires
an EIA and, if so, what level of environmental
review is necessary.

16. Initial Environment ExaminationEnvironment Examination
Initial environmental examination (IEE) is
intended as a low-cost environmental evaluation
that makes use of information already available.
It boost up the process of EIA and lead the
matter to further assistance.
17. IEE in the Overall EIA Process
Project
Screening
Identifies projects that
typically contain potential
significant issues
Initial Environmental Examination
1. Identifies potential significant
environmental issues associated
with a project
2. Grades effects and identifies actual
Significant Environmental Issues
(SEIs)
3. Resolves simple SEIs
4. Recommends further action for
resolving outstanding SEIs
Full-Scale EIA or Other
Additional Study
Resolves any remaining
significant environmental issues
18. Scoping
A process of interaction between government
agencies and project proponents
Identifies:
– spatial and temporal boundaries for the EIA
– important issues and concern
– information necessary for decision making
– significant effects and factors to be considered
– Establishes terms for reference of full scale

– Select appropriate mitigation measures
– Residual impact significance
22. Decision Making
• The challenge of making the final decision on
implementing a project is observed.
• Decision are taken at all stages during the EIA
process and the outcome will be based on these
decisions.
• If a large scale project falls under the jurisdiction
of countries with comparable national EIA
procedures,it should be feasible to be more
ambitious in organising EIA Transboundary..
23. Monitoring
In legislation there is a often demand for
environmental reporting when treating
permits to activities with large EIA.
This stage involves improvement and
mitigational measures to put forward EIA.
It also involves elements of assessing
risks and hazard management.
24. Audit and Evaluation
• This is the final stage of EIA.
• Audit consists opinions and corrections of
the report which are submitted in front of
decision making committee.
• It also reveals that whether EIA is
necessary or not for the report submitted,if
necessary what are the measures taken in
order to overcome the drawbacks and
hazards..
25. Uses of EIA
Systematic evaluation of a eco friendly
project.
Risk and hazard assessment.
Impact identification.
Monitoring of impact and advice.
Development control
Project development
SEA(strategic environmental
assessment) and permit.
26. CONCLUSION
EIA is an important tool in assuring that
projects and plans will not give adverse
impact on the environment.
The use of EIA has developed
throughout the world and may different
applications exists.
EIA process thus could not only prevent
costs due to environmental aspects but also
prevent possible public opinions and protest
against a project.

FLOW CHART LINKING THE FUNCTIONS OF PROJECT SCREENING INITIAL ENVIRONMENTAL EXAMINATION AND ENVIRONMENTAL IMPACT ASSESSMENT
1. OVERVIEW
This slide shows the functional linkage between these three steps in the Environmental
Impact Assessment process.
2. PROJECT SCREENING
Project screening identifies the projects that typically contain potential Significant Environmental Issues. The projects are identified, or selected, using screening criteria based on project type, size, and location. Projects that are selected must pass through an Initial Environmental Examination (IEE) so that Significant Environmental Issues (SEIs) may be identified, and when possible, resolved.
3. INITIAL ENVIRONMENTAL EXAMINATION
The IEE performs four important functions.
1) It identifies the potential SEIs associated with a project. These potential SEIs are effects on environmental resources that may result from various components of a project. They may be related to the design, the construction, or the operation phase of the project.
2) It determines the actual environmental issues for the specific project and grades them according to their significance and whether or not they may be resolved within the scope of the IEE.
3) The SEIs that are simple enough to be resolved within the scope of the IEE are pursued. Environmental protection measures and an environmental management plan are developed. Projects for which all issues have been resolved in the IEE use the IEE in place of an EIA.
4) For SEIs that cannot be resolved within the scope of the IEE, recommendations are made for the work required for resolution.
4. THE EIA
The EIA is used to resolve complex environmental issues. The IEE is very important for the EIA because it focuses the tasks to be performed in the study on specific complex issues, and develops the background on these issues. The EIA is a much more efficient study when it can draw on the work of the IEE.

FLOW CHART OF TERMS OF REFERENCE, INITIAL ENVIRONMENTAL EXAMINATION, AND FULL-SCALE EIA
1. OVERVIEW
This slide shows the inter-relation between the Initial Environmental Examination, the Terms of Reference, and the Environmental Impact Assessment. Through this process, the significant environmental issues which remain unresolved in the IEE are linked to the study area resources which may be impacted. The research and analysis of resource impacts are the tasks to be performed in the EIA.
THE TOR:
1) Delineates the study area;
2) Lists the significant issues and the related resources to be investigated and describes how the findings will be presented;
3) Details a work plan for the EIA so that the process will run smoothly, on time and within budget.
